Abstract (en)
This invention is connected with the idea of finding methods that can be used for the exploitation of the two half-periods of a motive force that is moving in a rotatory sine motion or in a straight sine motion in order to move a body in a one-direction rotatory motion [other than the well-known method, (the method of the wheel and the decentralized straight piece)] in case of the straight sine motion. These are eight essential methods, four of which are for the rotatory sine motion and four are for the straight sine motion. These methods can be applied in any mechanical case that depends on the transmission of motion from a rotatory sine motion (or straight sine motion) into a one-direction rotatory motion. That is useful at least in the following fields: 1- Exploiting the time which is often wasted, and which often passes without any production, during the half period of the sine motion. 2- Sparing (or exploiting) the power exerted during that wasted time. An applied example of this invention is the double ratchet-spanner, or double ratchet screw driver. <IMAGE>
